Density is mass divided by volume. Assuming the mass doesn't change, if the density decreases, then the volume must increase.
When a material expands, its volume increases while its mass remains constant. This causes the density of the material to decrease because the same mass is now spread out over a larger volume, resulting in a lower density.
When the density of a fluid increases due to heating, the molecules within the fluid move faster and spread further apart, causing the fluid to expand. This expansion leads to a decrease in density, as the same mass now occupies a larger volume.
When the density of a fluid gets hotter, it usually decreases. This is because as the fluid gets hotter, its molecules gain energy and move farther apart, causing the fluid to expand. This expansion leads to a decrease in density.
When the volume increases and the mass decreases, the density of the object decreases. This means that the object becomes less compact or dense for the given volume. The relationship between volume and mass is important when considering the physical properties of an object.
If the volume of an object increases but its mass stays the same, the density of the object will decrease. This is because density is calculated by dividing mass by volume, so if the volume increases without a corresponding increase in mass, the density will decrease.

It gets smaller.
As y gets, smaller, x gets larger.

When air gets hotter, or when any gas gets hotter, it expands. This means its density will decrease; therefore, cooler (and heavier) air will push it up.When air gets hotter, or when any gas gets hotter, it expands.

Density increases until 4 degrees of celcius.Then decrease again.

If the mass stays the same, then when an object gets larger, its density decreases. The larger density=the more bouyancy

it gets smaller and then there is no more energy to make it travel
